How Do You Buy A Radar Motion Detector?
Radar motion detectors emit a constant stream of microwave radiation and bounce that energy off the surroundings. The detector then compares the original signal to the reflected signal and notices changes caused by an object in motion. Here’s what to look for if you want to buy a radar motion detector. Plan out your use of the motion detector. Are you using this to trigger an automatic door, or just turn on a light? Different models will be better suited for different applications. Pick models that have a range and coverage angle sufficient for your needs. Some radar motion detectors can be focused on specific locations, while higher end models can detect motion even through an intervening solid object. Consider the advantages of hardwired power versus the convenient installation of battery powered models. Look for a radar motion detector with a sensitivity control so you can screen out false alarms caused by pets. Make a budget for the purchase. Do a quick browse of available models t
